[ovirt-users] Passwordless SPICE console login?

Hi, we have all VMs set up with passwordless users, using only keys for remote ssh login. When connecting through SPICE console, it prompts for login. Using something like root/ubuntu with empty password does not work. Is there a way to do this with keys or is it essental to have a local user with password (perhaps with restricted SSH) to perform a console login? Best regards, cen
